When underfed during flowering the plant will take nutes from the fan leaves to get nutes to the buds. I'm guessing that is what is going on with yours. On your next grow you will want to increase your feed rate when you start to see the shine come off the leaves and color fading.

Nitrogen deficiency. Usually happens towards the end of flowering naturally, but if your trichomes are still clear, I would give it some N. If possible, adding light in the 6500k range should help also.

Here is an article by dj short about breeding and it mentions hollow stems.

Here is the cut and pasted part.

The next criteria for elimination is borrowed from Michael Starks' book, Marijuana Potency, and involves stem structure. Large, hollow main stems are sought while pith-filled stems are eliminated. Backed by years of observation, I agree that hollow stems do seem to facilitate THC production.
